The top of the obstacle is a tornado collar secured, not sealed, to the smokeshaft. Over the ceiling, the air and vapour obstacle is twisted around the drywall to get in touch with the firestop sealant.


A collar-like ceiling trim plate is connected listed below the firestop. Work securely around electrical wiring (switch off the power).

A heavy polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encloses the electrical box. An electrical wire leads away from the electrical box and down via an opening right into an indoor wall. Openings around electric wires are loaded with caulking or foam sealer, and caulking seals gaps along the top of the indoor wall surfaces.


Attic air flow serves a number of objectives. It minimizes summer warmth accumulation, prolonging the life of roof covering and minimizes air conditioning system loads.

There is usually a void in between the celebration wall surface (such as the common wall between devices in duplexes, triplexes and row homes) and the side of the attic flooring.


A hefty polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling frames the electrical box.

This proportion refers to unobstructed air vent area to the protected ceiling area.


Do not make use of electrical exhaust followers for attic air flow as these can draw more air than can be supplied through the soffit vents. This will in fact draw residence air right into the attic room, resulting in greater heat loss and dampness buildup. They are also prone to failing, sound production and raised power usage.
